CLOSURE FOB DISGHARGE APERTUBES IN PACKAGES.

I To all whom it may concern:

Be it known-that I, CHARLES L. Wnm, a citizen of the United States ofAmerica, re-

' siding at Port Huron, in the county of St.

Clair and State of Michigan, have invented certain new and usefulImprovements in as salt, and it is the object of the invention toprovide a simple form of closure for an aperture in said. package .whichmay be readily opened for discharging the contents. It is a furtherobject to facilitate the pouring of the granular material by aconstruction of closure which when open directs the stream verticallydownward and prevents a lateral overthrow. With these and other objectsin view the invent1on comprises the '7 construction as hereinafter setforth.

' In the drawings:

Figure 1 isaperspective view of a box or carton provided with myimproved form of det closure, shown in open position;

Fig. 2 is a cross section showing the closure 1n closed position;

Fig. 3 is a similar view in open position;

Fig. 4 is a longitudinal sectional perspective view through the closureand adjacent portions of the receptacle;

Fig. 5 is a plan view of the receptacle showing the aperture thereinwith the closure removed; I I r Fig. 6 is a section illustrating the bythe closure; and

Fi is-a perspective view of the closure A is thebox or receptacle havingformed therein the discharge aperture B,'which is shown as arranged inthe cover of the box near the periphery thereof. This aperture ispreferably of substantially rectangular form being provided at one endwith an inwardl projecting ton e ortion C separated y slits D om e. ajacent side escrtions. E-is the closure referably form of sheet-metaland of a su ntially U-shaped cross section, being provided with a flatto F having a projecting lip G at one end, an

dependin sides-H. The latter are of. triangular orm having curved or talends I and at the opposite ends Specification-of Letters Patent.

1 open the closure, by engagin the finger nail beneath the projectinglip' with the inner e' pivotal motion of g tongues projecting beyondtheend of the top portion F. These wings H are also preferably providedwith laterallydeflected flange ortions K at their lower ends, as shown mFig. 7. The closure E is so proportloned that the sides H will fitwithin the aperture B, the tongues J beingfirst in serted and hookedunder the cover at the ends of the slots D. The end of the top section Fwill lie over the tongue C and the opposite end having theoutwardly-curved 111) G, as shown, will overlap the opposite end of theaperture B. To first engagethe closure the sides H which are slightlyresilient are sprung inward enough to pass the laterally-deflectedflanges K within the a erture, and upon releasing the pressure thesesides will spring outward so that the flanges K will'form stopspreventing disengagement of the sides.

With the construction as. described the top portion'G of the closurenormally lies flat upon the cover of'the box overlapping the ends of theaperture B, and its sides fitting tightly against the sides of theaperture, thereby forming a tight fit. The friction is suflicient tohold the parts inthis position even where the box A is inverted. To

of the closure E the latter may be raised until the stops K preventfurther movement. The material may then be poured from the box, 'in Fig.6, the closure forming a. which revents the stream from shooting out asshown late y and compels a vertical downward mrgeme'nt. f h J y reason 0t e projectin tongues on the closure and the tongue 0 on the box cover apivotal engagement is secured without hen or stressing the parts.- Thesides H may if desired he 10d ment of the closure and at the same time 7slightly concaved, as indicated at L, so as to relieve from frictionduring openingimovemaintaining a, tight fit in closed and openpositions.

What I claim as my invention is 1 1. The combination with a receptaclehavof, ad acent the edge-oi said face, of a closure or said aperturepivotally enga ed thereof, said closure ing outwardly. adwstable to adeflector ing position, and means. ouard Patented June ll, tflll.
